RGB (Red, Green, Blue) and hexadecimal (#RRGGBB) are two ways of expressing digital colours. RGB uses three components 0–255. Hex encodes each component as a two-digit base-16 number. HSL (Hue, Saturation, Lightness) is a more perceptually intuitive model used in design tools. All three representations describe the same colour space.
